This blog covers ACH IAT which creates a .dat or.txt file. It is assumed reader has basic knowledge on APP and is aware of FBZP configs.
Payment medium workbench cannot be used along with classic payment programs as shown below:

You will have data elements in place. you can choose the correct set of data elements from below structures:
For example- field name “immediate destination” in your bank format with 10 characters- the field will be UBNKL which is our house bank number- this field is from REGUH table. This field is a part of FPAYHX structure. Maintain bank number in FBZP configuration in house bank since this is our bank account number.

Maintain instructions as shown below. these are service codes in your format:
Assign this code to your house bank as shown below. Every time you make a payment using ACH this instruction key is defaulted. Another option is to update this instruction key in FB60 at the time of posting invoice; which is not possible during MIRO. hence it is advised to update this instruction at the house bank level.
