Does anybody knows how to deal with this variable.

I need to get the previous value of different fields that changed. Thanks.

I never had to use it there are other functions too.

Refer to-

get.prev.value() (http://www.baanboard.com/programmers_manual_baanerp_help_functions_form_and_form_field_operations_get_prev_value)

BaanERP Programmers Guide

stp.reset.value()
--------------------------------------------------------------------------------
Syntax
void stp.reset.value()

Description
This resets the value in the current field to its previous value. You can use this function only after input to the field.

Context
4GL library function.

You can use this function only in 4GL scripts. You can use it in the following event subsections:

on.input, after.input, check.input

In a check.input subsection, you cannot use this function before a save operation. To ensure this, program the section as follows:

check.input:

if not before.update.check then

stp.reset.value()

endif

I couldnt find this function on the online tools library here, have to ask Pat to check if this is the latest tools library version.

Thanks NPRao,

Do you know which dll hold this get.prev.value() function, caus ewhen I try to compile, it fails with unresolved reference to it.

I am not sure if thats available in your BaaN Version or not.

I didnt include any tools dll, I tested it in the Type-1/2/3 script and it just worked fine.

Sorry :eek:

I found a sample code in one of the scripts, hope it helps you out.


field.sort.totals:
check.input:
if sort.totals > 3 then
message("Only 1, 2 or 3 allowed")
sort.totals = lval(attr.previous$)
input.again()
endif

Try using following functions -

on.change.check()
off.change.check()
changed()
not.curr()

Hope this helps.
