    Hi,

    Pls find the details as below :

    Discontinued Parts

    Use

    You can determine in engineering/design that a material is to be replaced by another one at a certain point in time. When replacing a component with another, however, the stock of the old material should be used up before the new one is introduced in order to avoid dead stock.

    It may be necessary to replace one part for another if:

    one part is replaced by a more technically advanced part

    an expensive part is replaced by a less expensive part

    The task of MRP when discontinuing parts is to reassign the dependent requirements for the component to be discontinued to the follow-up material, once the stock of the part to be discontinued has completely been used up.

    The system differentiates whether

    exactly one material is to be replaced by one follow-up material (simple discontinuation), or

    a group of materials is to be replaced by another group of materials (parallel discontinuation).

    Prerequisites

    Both the part to be discontinued and the follow-up part must be MRP parts.

    The base unit of measure of the follow-up part must correspond to the base unit of measure of the part to be discontinued

    Both the part to be discontinued and the follow-up part must be either a stock item or a variable-sized item in the bill of materials

    The follow-up part is not a phantom assembly.

    You have defined a main material to be discontinued for parallel discontinuation. When the stocks of this material are used up its dependent requirements and the dependent requirements of the rest of the materials in the group are reassigned.

    You have entered the following data in the material master (MRP 4 view) for the material to be discontinued (in parallel discontinuation: for the main material to be discontinued):

    Indicator 1 for Single/parallel discontinued part/material

    Follow-up material

    Effective-out date

    In parallel discontinuation, you set the indicator 3 for Dependent parallel discontinued part/material in the material master for materials dependent on the main material to be discontinued.

    In parallel discontinuation, you have defined the link between the parts to be discontinued and the follow-up material in the BOM:

    All parts to be discontinued and all follow-up materials have been entered in the BOM.

    Parallel discontinued parts have the same discontinuation group. You enter these in the BOM item.

    The follow-up parts are set to the follow-up group. You also enter these in the BOM item. The follow-up group key is set correctly with respect to the discontinuation group.

    You can find further information on this in the SAP document PP u2013 Bills of Material.

    Features

    During the planning run, the system checks the discontinuation indicator and the effective-out date in the material master and reassigns the materials correspondingly. The system reassigns the requirements during the planning run for the discontinued material and not during the BOM explosion. The system reassigns only dependent requirements and dependent reservations.

    Reassigning Dependent Requirements

    Starting from the effective-out date, no new procurement proposals are created for the material to be discontinued. Once all the stocks of this material have been used up, its dependent requirements are reassigned to the follow-up material. If there is still enough stock of the material to be discontinued to cover a part of the dependent requirements, this stock is used and the rest quantity is reassigned to the follow-up material.

    In parallel discontinuation, you use the indicators in the material master and the link in the BOM to instruct the system to discontinue all materials in the group when the stocks of the main material to be discontinued have been used up. How the dependent parts react depends completely on the stock of the main material to be discontinued. These dependent parts are replaced once the stocks of the main material to be discontinued have all been used up. The dependent requirements are then reassigned to the follow-up materials.

    Additional Requirements

    Additional requirements created after the effective-out date are not reassigned and no new procurement proposals are created for them. The system sets the Uncovered requirement after effective-out date exception message. This applies to the following requirement types:

    Manual reservations

    Independent requirements and forecast requirements

    Sales orders

    Requirements for subcontracting

    Safety Stock

    The safety stock is not used up after the effective-out date because safety stock should also be maintained after then to cover unplanned requirements such as a requirement for a replacement part.

    The system therefore reassigns the dependent requirements to the follow-up material even if safety stock is available. If the stock level drops below the safety stock, the system also creates a procurement proposal for the discontinued material after the effective-out date. The system issues the Receipt after effective-out date exception message for the procurement proposals.

    If you want to consume the safety stock, you can set the safety stock to 0 in the material master on the effective-out date.

    Fixed Receipts

    When discontinuing parts, the system does not include fixed receipts such as order proposals or production orders if they are after the effective-out date. The system issues the Please cancel and Receipt after effective-out date exception messages.

    Hope this clears your doubt.

    Reward if useful.

    Regards,

    Tejas

    Hi,

    If this indicator is set, the system transfers the dependent requirements in materials planning to the follow-up material if they are no longer covered by warehouse stocks. However, this requires:

    • The part to be discontinued and the follow-up material to be planned using material requirements planning (MRP)

    • The base unit of measure of the follow-up material to be the same as that of the part to be discontinued

    Hope this will be useful.

    Hi,

    Assume you want to discontinue one material and it should replace by another material. For this situation you can use this.

    In discontinued material master MRP4 view make tick mark in discontinued indicator & input the effective date. In follow up field enter replace material.

    After this date system will plan for follow up material while MRP run.

    Regards,

    Dharma

    Hi Sarfraz,

    Discontinued materials in SAP means:

    If you want to use some of the components in place of the original components & these original components , you are

    no more using.

    In the material master if you enter discontinued material

    system will prompt you to give effective out date.

    That means from which date you are going to use the substitute material.

    These fileds are in Material master MRP 4 view.

    .

    1) Follow-Up Material:

    Number of the material that the system uses in materials planning to replace the material to be discontinued once its warehouse stock is depleted.

    Use

    In the material master record and also in the bill of material (BOM), you can define a follow-up material for a material to be discontinued. The follow-up material defined in the BOM has a higher priority than that in the material master record.

    Procedure

    You must always specify a follow-up material in the material master record for the system to know a follow-up material if none has been specified in the BOM.

    Dependencies

    Simple discontinuation

    A component to be discontinued is replaced with a follow-up component at a particular date.

    In the material master record of the component to be discontinued, you must set discontinuation indicator 1, enter a follow-up component, and specify an effective-out date.

    Dependent parallel discontinuation

    A group of materials is replaced with a group of materials; that is, if one component is to be discontinued (the main component), another component must also be discontinued (the subordinate component).

    In the material master record of the main component to be discontinued, you must set discontinuation indicator 1, enter a follow-up component, and specify an effective-out date. In the material master record of the subordinate component, you must set discontinuation indicator 3.

    2) Discontinuation indicator

    Identifies the material as a part to be discontinued and includes it in the discontinued parts procedure in materials planning.

    Use

    If this indicator is set, the system transfers the dependent requirements in materials planning to the follow-up material if they are no longer covered by warehouse stocks. However, this requires:

    a)The part to be discontinued and the follow-up material to be planned using material requirements planning (MRP)

    b)The base unit of measure of the follow-up material to be the same as that of the part to be discontinued

    Please award points if you find it useful

    Hope it is clear.

    Regards,

    R.Brahmankar
