Hard topic on LIS

Hello experts,

I hope that an expert could help me.

I've created a LIS structure for QM. Everything works fine except 2 points :

• I'm not able to make a average on total line, (ex : number of days

line1 - 3 days

line2 - 6 days

line3 - 9 days

total = 18 days and I would have 6 days

• when I make a QA12, the system creates a second line with empty information

Standard system reaches to make an average (for example in MCXA with S069 structure) but not me.

I'll reward any help on this topic.

Regards,

Christophe
