CNV_OT_APPL_PE045 - Overview

• Message type: E = Error

• Message class: CNV_OT_APPL_PE - Messages for application specific functions

• Message number: 045

• Message text: Value preparation to screen format for field &1 with value &2 failed

What causes this issue?

Prior to calling the function POSTING_INTERFACE_DOCUMENT within function
module CNV_PE_POST_FI_RFBIBL all incoming data is moved in an internal
table FTPOST of type FTPOST.
Each record of FTPOST represents one screen field of transaction &V3&
with its value.
The value itself must be present in the format that is expected on the
respective screen field. Therefore (within CNV_PE_POST_FI_RFBIBL) each
value is prepared to match the screen input format.
This preparation failed for field &V1& with value &V2&. Instead the
value is passed unchanged into POSTING_INTERFACE_DOCUMENT function
module.
