  1. Input Check of the service Lines.

You can carry out input check when service lines are entered. There is also the alternative to prepopulate individual fields of service lines or overwrite these with a fixed value.

The Enhancement SRVESLL consists of two user exit that are called at different times.

  • EXIT_SAPLMLSP_030

This exit runs before the standard checks are carried out

  • EXIT_SAPLMLSP_031

This exit runs after all the standard checks are carried out

You can use EXIT_SAPLMLSP_30 to prepopulate the fields of the service line, for example we need to populate field USERF1_TXT. If you want to create implementation of this user exit you can follow the way we mention before.

You can use input check in EXIT_SAPLMLSP_031 to carry out custom input check because it will only run after the standard checks are called.

In this example we need to check USERF2_TXT that emtpy values are not allowed and error message will be shown.

  1. Prepopulating Header Data in SAP External Service – SAP Enhancement.

When you create a new data via ML81N transaction code, some header data must first be filled out before the services can be entered or copied from service purchase orders.

You can use enhancement SRVESSR ( EXIT_SAPLMLSR_010 ) , for the example we need to prepopulate ESSR-TXZ01 .
