How to add new custom field in "SEPA Credit Transfer Initiation Template"

Hi Team,

We need to add custom field in this template.

Below are the details.

Suppose we do payment for particular supplier in AP and select multiple invoice(e.g. 5 invoice) at the same time then in iby_payments_all table goes only one records but in iby_doc_payables_all

table goes 5 records as per selected invoices so we need to show count of invoice- 5 in this template.

Can you please help me.I already attached ".xsl" template

Thanks,

Bhatt
