GESAMT EINHALT./ERST

13:24 Mar 31, 2015 

I think you are both correct. "Einhalt." is most likely something like "Einbehalt" or "Einbehaltung", while "Erst" refers to "Erstattung". This whole document is riddled with inconsistent abbreviations, both with and without periods, leaving the reader wondering if in fact it is an abbreviation. Hans-Jochen, if you will post your suggestion as an answer, I can award you points. Only well deserved, in my opinion. Dianaft, thanks for the great link, it confirmed Hans-Jochen's suggestion, and it a great resource for other abbreviations!

"Einhalt." might play on an old use of the verb "einhalten", in the sense of "einbehalten", and "Erst" would be short for "Erstattung". My suggested translation for the latter may not be quite right but should be close. "total amount withheld/due employee" is another way of making sense of it. Here is a list of "Lohnarten", including 889:

That list may not be universal, i.e., 889 may be different item. Here is a sample payslip:

which may be using "Be-/Abzüge" in the place of "Einhalt./Erst.", the essence being sums counting one way or the other.

Actually I would need the full term. I suspect it is a complete expression regarding the paystub information. And Einhalt. is an abbreviation as well, since it has a period at the end.
