Thanks Alex, for your quick responce.
No I am not on the level of Payables yet; just hanging into AC 306 and seem to have problems to get it right (yet).

We did already some recurring stuff on the Tasks but that in this format would do.

I have a number of techniques that has to be trained regurely and within each technique a number of exercizes:
T-A has about 6 exercizes, T-B 4, T=C 180. And should work the Techniques through every day with within every "T-" every day the next "Exc".
Most importantly for now is that I would have a way to store the ExcID and at the next training the Program should provide me ExcID+1.

If I could get this working the next thing to try is to train the Exc-es in random order (within their "T"range.

I hope I made it understandable.

Thanks again
