RM06EEI0 - Net price must be greater than 0 - error
After much searching to find an answer for this and without being able to find anything that worked for me, now that I have resolved my issue I thought I would share my finding!
The reason I was getting this error is due to the way in which RM06EEI0 reads in values.
We were entering in the file a quantity of 1 at a price of 1 GBP, however (if the error message didn't stop it from posting) in SAP this was looking like a quantity of 0.001 at a price of 0.01 which is small enough that SAP gives the zero value error message.
For us therefore, converting the value to a quantity in the input file of 1000 (which really is 1.000) and a price of 100 (which really is 1.00) has solved the issue.
Hope this helps anyone else who comes across this problem!
