Predicates for XPath in Condition Editor of NWDS for PI AEX 7.4 (SP 7)

$

Dear all,

 

we are in the middle of migrating from our old Dual Stack PI 7.0 to our new PI 7.4 AEX.

 

We have a fairly largen receiver determination on the old system that makes heavy use of predictes. One expression for example looks like this

(SHPMNT05/IDOC/E1EDT20/E1EDL20/E1EDL37/E1EDL49/E1EDL50[XSIQUALF='EEIVERF']/VLABDATA = 01)

 

However, when I'm trying to insert this in NWDS' condition editor there's an error stating "Predicates are only allowed with EXISTS operator"

 

1. Is this a limitation of the condition editor in NWDS?

2. Is there a way to configure the above XPath so it is working in NWDS?

3. Would it be safe / wise to configure the mappig in ICO in Swing Tool or would this be overwritten by NWDS configuraiton?

 

Many thanks

 

Jens
