Field in Flat File DataSource

Question

I created a Flat File DataSource.
In the DataSource, I enetered InfoObject 0OUTAGTARGT in the Fields tab ->InfoObject Template column. I want this InfoObject to be mapped
into field KTWRT (Target Value) in R/3 table EKKO.
However, when I enter the the InfoObject 0OUTAGTARGT and hit Enter key, system prompts me to copy the properties. I choose Copy.
And then it says:
Reference field 0DER_CURR was added automatically.
Now I have ORDER_CURR entered in the Field column, with InfoObject Template 0ORDER_CURR.
In the Field column, I replaced the field ORDER_CURR with WAERS (Currency field from R/3).
When I save it, I hit the following:
Missing currency field / unit field ORDER_CURR
System expect the field ORDER_CURR to be entered in the Field column. But in my source file, there is no field call
ORDER_CURR. It is actually WAERS.
How can I overcome this?

Answer 1

Maintain 0ORDER_CURR as it is needed by 0OUTAGTARGT.
Next, simply map WAERS to the ORDER_CURR field.
But it doesnt allow me to change. In DataSource ->Fields tab, I try to replaced the field ORDER_CURR with WAERS. When I click on Activate, I
hit the following:
Missing currency field / unit field ORDER_CURR
Please help.
