informatica - Schema connections is failing for optional field in a Infromatica b2b data transforamtion serializer -

i've created serializer in turn call embedded serializer xml edifact.

i've created schema connections. ideally connections should optional. i.e when there no data should fail.

for eg:

the input xml file :

data1

data2

for above field i've created schema connections:

connect(/abc/tag1,/ts_inspre/*s/bgm/*s/r01/*s/r01)  connect(/abc/tag2,/ts_inspre/*s/bgm/*s/r02/*s/r02) 

this work fine till both tags available, in case tag2 in not there solution fails error as:

[r303028] can't find value of '/abc/tag2'.

for business scenario both optionals .

please me resolve issue.

thanks,
