Need help with transfer routine.

Question

I am doing this enhancement in BW 3.5 version.
There is an object in ODS - > ZPATHNM (Pathname)
It gets data from ZPTDIR object.
Now, 0MATERIAL infoobject has text data. For PATH type materials it has descriptions like pt/dat/fafg.2.0 , pt/dat/ovg.2c ... so on.
The content after pt/dat/ for example fafq.2.0, ovg.2c is available in ODS object ZPATHNM (Pathname)
Since I have to extract PATH material numbers. So I created another object ZPATHMAT and mapping it to ZPTDIR.
I have to write a transfer routine when the 0MATERIAL text description had description beginning with pt/dat/ and the text after pt/dat/ is equal to data in ZPATHNM. i should get material number in ZPATHMAT.
This is the transfer routine, I have written between ZPATHMAT  and ZPTDIR . This is working fine.
Data : ZDIRNAM type String,
            ZCONT1 type string,
            ZCONT2 type string,
            ZMATERIAL(18) type C.
ZDIRNAM = TRAN_STRUCTURE-ZPTDIR.
IF ZDIRNAM is not Initial.
Concatenate 'pt/dat/' ZDIRNAM into ZCONT1.
  Select single MATERIAL
    into ZMATERIAL from /BI0/TMATERIAL
where TXTMD = ZCONT1.
RESULT = ZMATERIAL.
  ENDIF.
Now there is another requirement, where I have to create one more object, ZPATHDES. This object should get Material description for path type materials from 0PROD_HIER text table.
This object, 0PROD_HIER is an attribute of 0MATERIAL.
So the logic to get the material description into ZPATHDES, is when the material number in 0MATERIAL is equal to material number in  ZPATHMAT (generated from above routine), I should get description (TXTMD) from text table of 0PROD_HIER (/BI0/TPROD_HIER) into this ZPATHDES object.
I able not to connect this logic in the code and it is throwing errors.
I need help in coding.
Thanks.

Very hard to understand the logic in a thread. Can you please write your code, which is throwing errors? May be that will help us.
