Error message external customer invoice

Hello everyone, 

I have an error message when i want to to create an external customer invoice. 

I created a template with the model STDCIN and then i loaded it in AURENA. 

When i want to create this invoice (loaded → verify → created) i have an error message see below : 

Error message : The invoice amount in “dev compt” (accounting currency) does not match the account assignment amounts for item no. 1.

I have this error message but the amount is the same between the line and the posting :

Do you have any issue concerning this error message? 

I already did a lot of test, change the amount (gross to net and net to gross)! 

Best Regards, 

Jérémy,
