The requirement is to put validation on 'MATERIAL GROUP' at item level as well as service sub line item level.I have used EXIT_SAPMM06E_017 for line level validation.
For service sub line level 'MATERIAL GROUP' i tried using EXIT_SAPLMLSP_030 but validation is not working properly as
EXIT_SAPLMLSP_030 is triggered before EXIT_SAPMM06E_017.
Kindly suggest any alternatives.
Thanks in advance
