Example:

A payment posted to the module without a DPC 64 but was included in a manual TC 767 CRN 263 transaction AND an in-module credit transfer is input to add the DPC 64 causing the systemic TC 767 CRN 263 to generate with the amount of the payment, thereby double crediting the module.

Use CC REQ54 to input a TC 290 .00/ TC 298 .00 CRN 263 as appropriate, to generate a TC 766 CRN 263 to reverse one of the duplicate TC 767 CRN 263 postings.
