A coupon was billed in Sampling A/B under SC 01. However, the billed entity put it on Form C, e.g. due to overbilling.
The original billing party receives a Form C, the item in question being part of, with SC 51 and RC 3B.
If the original billing entity does redebit this coupon again it has to do so in non-sampling environment with SC 27.
What if the coupon actually is a FF document which should be billed under SC90? If such document is being included in SC 27 billings, how should the billed party identify it as FF coupon?
Wouldn't it be more appropriate to have an own source code (e.g. SC 28) for FF coupons previously billed under sampling and which are now being billed in non-sampling?
Thank you for consideration.
