Problem with UDF context changes

Hi experts,

i am facing a slight problem with my UDF:

the scenario is idoc to jdbc, my problem is as follow:

in my source I have:

IDOC

>E1EDKA1 1..1

>>NAME1 1..1

>E1EDP01 1..999

>>E1EDPA1 1..999

>>>PARVW 1..999

>>>NAME1 1..999

in my target i create as many segments than there is E1EDP01

The problem is for each E1EDP01 I have several E1EDPA1 that itself contains several times the couple PARVW and NAME1.

And my condition is as follow: in E1EDPA1, I have to take the value of NAME1 for PARVW = YZ or XZ, and the value of NAME1 in E1EDPKA1 if i dont find YZ or XZ in E1EDPA1

My udf works when in each segment it is true, but does not work when in one segment the condition is missing:

for example, I have:

IDOC

>E1EDKA1

>>NAME1=name_header

>E1EDP01

>>E1EDPA1

>>>PARVW = AB

>>>NAME1 = name_AB

>>>PARVW = AC

>>>NAME1 = name_AB

>>>PARVW = YZ

>>>NAME1 = name_YZ1

>E1EDP01

>>E1EDPA1

>>>PARVW = AD

>>>NAME1 = name_AD

>>>PARVW = AE

>>>NAME1 = name_AE

>>>PARVW = XZ

>>>NAME1 = name_XZ1

in my target I must have:

statementName

>statement_name

>>action

>>table

>>access

>>>field_name = name_YZ1

statementName

>statement_name

>>action

>>table

>>access

>>>field_name = name_XZ1

I manage to get the result with the following UDF

for (int i = 0; i < PARVW.length; i++) {
			if (("YZ".equals(PARVW<i>.trim()))){
				result.addValue(NAME_poste<i>);
				
			}
			else if (("XZ".equals(PARVW<i>.trim()))){
				result.addValue(NAME_poste<i>);
				
			}
			//else {
				
				//result.addValue(NAME_header[0]);
			//}
		}

but as soon as i uncomment the else part (in order to get the value of NAME1 in the header part when PARVW is not equal to XY or XZ), it does not work.

another example is :

IDOC

>E1EDKA1

>>NAME1=name_header

>E1EDP01

>>E1EDPA1

>>>PARVW = AB

>>>NAME1 = name_AB

>>>PARVW = AC

>>>NAME1 = name_AB

>>>PARVW = YZ

>>>NAME1 = name_YZ1

>E1EDP01

>>E1EDPA1

>>>PARVW = AD

>>>NAME1 = name_AD

>>>PARVW = AE

>>>NAME1 = name_AE

then I must have:

statementName

>statement_name

>>action

>>table

>>access

>>>field_name = name_YZ1

statementName

>statement_name

>>action

>>table

>>access

>>>field_name = name_header

hope I've been clear enough, any help will be rewarded,

thanks a lot,

Jamal
