Custom BADI calling from BPC DMPs

Dear All

We have one script logic, which has clear statement or set of data region followed by a custom badi.

However this scipt was there in default logic, however to improve performance we have placed this script logic in separate logic file.

we have tried to call this script from DMP, however when we link to allocation process chain it got failed.

could you please let us know, to which standard process chain we can relate to call this script.. There are no parameters to pass explicitly because we are scoping everything in script logic.

please advise

thanks in advance...
