Customer fields are not available in the mass maintenance (Transaction MASS), i.e they can neither be selected nor changed. This is due to the program design.
Mass maintenance consists of 3 logical program components:
1. Initial screen (-> program SAPMMSDL)
2. Selection (-> function group MASS_TC)
For you to be able to edit customer fields in the mass maintenance, customer fields would have to be passed on from the initial screen to mass maintenance to data backup.This is not the case in the R/3 Standard System.
Customer fields are not changed in the mass maintenance, even if the customer fields have been included in table MASSFLDLST. Customer fields can then be selected in the mass maintenance, but changes to these fields in the program are not passed on to data backup.
Implement an individual solution.
Example: Transaction MM17 (mass maintenance material master)
- Data is saved in Transaction MM17 using function module IDOC_INPUT_MATMAS01.Notes 44410 and 116311 and their related notes describe how you can save customer fields in the material master using the function module.
- Material master module IDOC_INPUT_MATMAS01 is called from the mass maintenance using function module MASS_MATMAS03_CHANGE.Customer fields can only be changed via mass maintenance if the newly created Idoc structure for customer fields is filled with data before IDOC_INPUT_MATMAS01 is called in module MASS_MATMAS03_CHANGE.
Support can be made available after an individual case check within a consulting solution.
