hi,

sorry it was my fault. i mean following:

SPT_SK_PROJEKTNUMMER_KKKK = AAAA
SPT_SK_PROJEKTNUMMER_AAA = BBB
SPT_SK_PROJEKTNUMMER_NNNN = CCCC
SPT_SK_PROJEKTNUMMER_BXXX = DDDD
Projectnumber:
AAAA-BBB-CCCC
or
AAAA-BBB-CCCC-DDDD

However if the Parameter SPT_SK_PROJEKTNUMMER_BXXX is “” than i get

AAAA-BBB-CCCC-

thanks

@Domi1982

SPT_SK_PROJEKTNUMMER_KKKK = AAAA
SPT_SK_PROJEKTNUMMER_AAA = BBB
SPT_SK_PROJEKTNUMMER_NNNN = CCCC
SPT_SK_PROJEKTNUMMER_BXXX = DDDD

All those parameters are always available?

BTW, can you show me some outputs in youre project?

[Domi1982]

Yes they are always available!

They are only text parameters. I need them for the exprot into a planlist…
for Example the SPT_SK_PROJEKTNUMMER_BXXX is empty

the output

but there ist one “-” to much

[jw.vanasselt]

Ah okay, in this example bxxx is empty. Is this the only parameter that can be empty or can all the parameters be empty?

[Domi1982]

Yes this one can be empty… it depend’s an the project…

thanks, but with this my result:

The “-” after the CCCC is away but now there is no BBB

[jw.vanasselt]

That’s weird. Is one of the nodes disconnect?
Look you script like this?

Please export your graph

NB: the node with the test inside give the right value as example.
