customer payment

hi all

I have an Issue where we are trying to do a customer payment, but the document was on a payment block 'X' which should have been on block 'Y' which is send for approval' as per the process, when i checked the customer master it did not had the intended payment method which i then changed. and then i changed the payment block on the document manually, but it still did not go for approval. how can i deal with this.

Do i have to create a new document entirely??

regards

Katya
