FetchValue
Mon 01 January 2018Syntax
FetchValue(scrollpath, target_row, [recordname.]fieldname)
where scrollpath is:
[RECORD.level1_recname, level1_row, [RECORD.level2_recname, level2_row, ]] RECORD.target_recname
To prevent ambiguous references, you can also use SCROLL . scrollname , where scrollname is the same as the scroll levelâs primary record name.
Description
Use the FetchValue function to return the value of a buffer field in a specific row of a scroll level.
Note: This function remains for backward compatibility only. Use the Value field class property instead.
This function is generally used to retrieve the values of buffer fields outside the current context; if a buffer field is in the current context, you can reference it directly using a [ recordname .] fieldname expression.
