Hi @mdeanton,
Try this URL- make sure to give the correct application server host and port:
https://myifsserver:48080/client/runtime/Ifs.Fnd.Explorer.application?url=ifsapf%3AfrmReceiptInfo_Ext%3FEXTERNAL_SEARCH%3DSOURCE_REF1%253D20KAN0240%2526RECEIPT_NO%253D1%2526SOURCE_REF3%253D2
What I have done here is encoding the URL as per the guidelines mentioned in F1 Documentation:
https://docs.ifs.com/techdocs/foundation1/050_development/022_user_interface/045_ee_dev/080_external_search/default.htm
Refer to this document to learn how to format the URL correctly. To encode the URL, you can find a free online encoding tool. There are many.
An example would be https://www.urlencoder.org/. Use at your own risk. Make sure to set the character encoding to “UTF-8” and newline separator to “CRLF Windows”
Hope this helps!
