Shopping Cart workflow retrigger for changes done to SC already created
A shopping cart is created and later on in "Check Status" when the shopping cart is opened in change mode and any changes are made to the shopping cart either header or item level, the whole approval workflow is retriggered and the approvers are determined again.
We have a scenario where for a particular account assignment category the approvers are added manually - ad hoc approvers through the "Add Approver" in "Approval Preview". For these shopping carts with manual approvers when in "Check Status" any changes are done to header or items of the shopping cart, the whole approval workflow is retriggered and the manual approvers previously added are refreshed as per standard SAP.
I have to put a check in DOC_CHECK badi for the existence of approvers. If no approvers found an error message has to be thrown for adding the approvers manually. I am doing this by reading the approvers from the container for a cart created already. But when changes are made and the workflow is retriggered, the workflow container contains only the previous approvers and not the refreshed ones. So this is not captured in DOC_CHECK badi.
Is there any way to capture the retriggering of workflow in DOC_CHECK badi, so that the check for approvers works fine even after a change being done to a shopping cart which is already created.
Thanks and Regards,
