How to trigger workflow for credit line items?

Hello everyone,

I have a requirement for credit/debit workflow approval. Here my challenge is to trigger the workflow for each and every line item of credit/debit. I have created a status profile and planning to develop the workflow through status management but could not find a suitable business object to delegate. i am getting error in BSVW when i use ZBUS2094 (delegation of credit object).

Is there any other way for this development? Any compatible BO to get line item data ?

Thanks in Advance
