Extending Material Master with Customer-specific tables


I want to use ztables in Material Master (Not append structures for any standard Material Tables) since I need to maintain country specific rates in MM01/MM02/MM03.

Is integrating customer tables in MMaster is advisable?.( OSS Note 1440 says can't integrate customer-specific tables in MMaster with out modifications to MMaster)

If we update ztables in MMaster, what are the impacts?.

Appreciate your expert comments.

    We updated table MARA by an append structure and used the management to create an own screen sequence to insert a custom tab where our custom fields are updated.

    See MM customizing to do that:


    Material Master->

    Here's How (Quick Guide Using an Example)

    If you want to use a ZTABLE I think the problem is where and when storing the data in database, because you should do that when the data of standard table are stored.

    So long as you can maintain consistency in data updates in database I guess there is nothing to restrict it .

    Now the question where and when to update the Z table so that data is consistent . An update should be done only when update to a standarad table is done . Have you heard of BTE ( Business transaction event ). Material master has one . Check in transaction FIBF -> Settings -> P/S Function Modules -> of SAP Appl. If you can find an event 1250 here then you can use this . This BTE is provided for extracting data for SAP APO etc . But this is kind of an exit which you can use to put your code for updating Z tables . Read OSS 188925 for reference and more info on this BTE.

      Hi Thanks for your comments.

      I did extending SAP standerd tables for Material Master with append structures. My case is strange. I have to use ztables, since I need to show multiple rates in tabular form in one of the main MMaster data screens (Not secondary screens). My questions will be clear for who configure MMaster. I did configure my Masterdata and now struguling to add country specific data in tabular columnusing table control. For example in MMaster Basic data view I want show table control.

      SAP maintain specific data screens for MMaster.If I use table control subscreen on main data screen, short dump occuring. If any body has an idea how to solve, pl reply.
