Source Determination does not happen automatically for Service Activity
We want to use material type DIEN with the ability of Service Entry
Sheets. Item category "D" (Services) can however not be changed to
allow the entry of ba material number.
Does SAP have the ability to create Service Entry sheets for a material
If you are using item category D then you cannot use Material of type DIEN. but you cannot have source list. But it has its own way of determining source. Check ML98. The reason why it do not have sourcelist is services are not as same as material every time.
If you are using Material of type DIEN you cannot have service entry but you can have goods receipt which is as same as service entry sheet. You can have source list
Depending on your requirement you can use any process. You will have same accounting entries and same work.
DIEN is not a replcement for Service masters. When you use service master becasue opf its inherent design we have to use D to proceed further. But The purpose of DIEN is entirely different , we can have a service material master and can maintain all the atributes related to a normal material including source list. Using DIEN material we can only have Goods receipt via MIGO. We can not use D here since it is having material master. Similarly we can have ML81N inplace of MIGO if we are using service master/ D combinaiton in a PO.
For the services used with item category D. You have to create a service master in AC03 for the service line items for service entry sheet.
Because DIEN is used in different perspective.
Services are internally supplied or externally supplied by the vender. Service master will not have the storage information.
The services can be invloved in activity such as garbage collection, consulting and leagal consutling.
Basically DIEN is material type used for the services which we r providing to our customers. If u want to treat services also just as materials, then copy the mat type DIES and create ZIEN and accordingly change the Views for this mat type. In this case we need to do the GR instead of SES.
For services its always advisable to go for either Service masters or PO with text. If we treat service also as material, then it will create a problem during scheduling of the service perticularly if u r using PS module.
