MRP after Material transfer

[ibrachka]

Dear experts,

My client wants to implement MRP for external procurement materials. The actual process of procurement ( without MRP) is to procure a root material and then do a transfer to other materials with mvt code 309 destined for sales through different distribution channels.

The MRP should calculate the requirements based on the root material, the issue is that the stock of this material is reduced due to the transfers. Therefore the requirements will not be correct.

Does the standard permit to implement MRP for this kind of procurement ?

Your guidance will be appreciated.

Hi Ibrahim, I do understand the issue. However I am quite positive you are not going to get desired effect with the config itself. There are user-exits in the are of MRP that you might use to change PR proposal. However I do question the way material 1 is "scattered" into material 2 and 3 with 309 movement type - let's leave that issue here.

If materials 1, 2, 3 are interchangeable you might consider using MPN-MRP sets: https://help.sap.com/doc/saphelp_dimp50/5.0/en-US/7f/a7e7434d6011d2b438006094b9c9be/content.htm?no_c...

Also take a look on how interchangeable parts work with MRP: https://help.sap.com/doc/saphelp_dimp50/5.0/en-US/5a/2b68ef4ed811d2b439006094b9c9be/content.htm?no_c...

Also consider that the above functionality is available in DIMP industry solution and requires activation in SFW5 transaction.

HTH, Best regards

Why do you use 309 transfers at all? If your business process implies changing "root" material into "sales" materials you should go through production orders. Then MRP planning is going to run smoothly.

Why should we use production orders ? this material is externaly procured, it doesn't go through any production process, the "root" material can be sold as well.

The problem here is that the stock of this material is scattered into other materials, exemple :

unrestricted stock of Material 1 (root) : 1000 PC

unrestricted stock of Material 2 : 500 PC

unrestricted stock of Material 3 : 250 PC

If the independant requirements of Material 1 are 2000, then the MRP should consider the 1750 of available stock and create a PR of 250 PC. Is that possible ? Normaly, through the actual configuration, the system only consider 1000 of available stock and create a PR of 1000 PC.

I hope this clarifies the faced issue.
