Strip blank spaces at begin of the field value
I am using standard XSLT mapping provided by SAP for SAP SNC and SAP ECC integration(Proxy->PI->IDOC).
I have a field that is coming with padded blank spaces and i have to remove that before mapping to Idoc in XSLT mapping.
I am using below function to remove blank spaces but nothing is working. Seems to be i am placing at wrong place or i syntax might be wrong.
Please help me to fix this issue.
