Fields to be updated in EGERH including primary key

[Former Member]

hi Experts ,

We have requirement to update standard fields in EGERH table. Creating custom program seems to be only alternative . I also referred :

Requirement includes chages in 'BIS ' and 'AB' and some other fields of EGERH .

The problem is with the BIS field.

It is primary key so even if I have to update EGERH , I have to delete the existing entry and insert new . However when device is installed , other ISU tables like EASTL , EADZ etc are also updated with 'BIS' as their one of the primary keys . I see a problem there. How can we update EGERH without impacting consistency in the system .

Please check if any ISU-FM's can fullfil your requirement ...

• ISU_S_DEVICEMOD_CHANGE
• BAPI_EQUI_CHANGE

I'm not on a SAP System right now but you can use ISU_*-Function modules for this.

Several points:

1. The requirement sounds poorly thought out, my recommendation is to push back with a standard approach to update the required fields. Such as device modification, technical removal/install etc. The reason you are using ISU is to leverage the fact it is a well designed ERP.
2. what are the fields required to be updated? it may be there is a standard solution to your requirement, without knowing more its nearly impossible to assist (except to critique the requirements)
3. While not released, ISU_DB_V_EGER_UPDATE is probably fit for your purposes.
