COFP clearing of Special GL item does not update value type 57

[anurag_bhandari]

We have project cash flow functionality implemented in our system. The issue we are facing is as below:

We have a billing document with 2 customer line items: 1st line item for normal customer receivable and 2nd line item for customer retention (special GL transaction).

The PCF document associated with this billing document also has 2 line items, both with value type 54 and debit amounts.

When we do a partial receipt against the 1st line item and then when we execute the CJFN transactions, one more PCF document is created for the original billing document.

This new PCF document has 2 line items with the partial receipt amount and the value type 54 for the first line item with credit and value type 57 for the second line item with debit. So at this moment in time the PCF report amounts are correct.

However, when we do a partial receipt against the retention amount and execute CJFN, there is no effect in PCF. No new PCF document is created and now the PCF report shows wrong values as we have received partial payment against retention which is not shown in PCF.

Commitment item for both GLs (customer recon and spl gl -alternate recon) is same.

Any idea why the PCF document is not getting created for the partial clearing of the special GL line item?
