Cross-company stock transfer: Condition P101 in billing document twice

Dear gurus,

we bash transverse institution banal transportation orders (STO). The process works conscionable fine, but we came on 1 unusual thing:

For billing, we defined a pricing process akin to modular ICAA01, but with conscionable 1 (!) terms condition, information benignant P101. Price root was acceptable to A (Purchase Order) to transcript the information worth for P101 from the STO to the billing document.

Now, erstwhile we make a billing document, determination are 2 (!) rows for information benignant P101.

The archetypal 1 is marked reddish (incorrect), it has a worth of zero. Further values:
Condition class: B Prices
Calculat.Type: C Quantity
Condit.Category: H Basic price
Cond.Control: A Adjust for quantity variance
Condit.Origin: A Automatic Pricing
Inactive: X Inactive vie formulas oregon incorrect

Now my questions: Why is the archetypal enactment generated and wherefore is it incorrect?

Any ideas?

Thanks
Jens
