FM: PRICES_CHANGE error

Hello All,

I am using the FM <b>PRICES_CHANGE</b> and <b>PRICES_POST</b> to update material master prices. Table <b>T_MATPR</b> in FM is a deep structure. I am getting error when I am trying to pass the values to the CR sub table of table <b>T_MATPR</b> in FM <b>PRICES_CHANGE</b>. ( PP sub-table is working fine.)

when i do this for CR sub-table

<b> it_matpr-cr-waers = t001-waers.</b>, i am getting error..The data object "IT_MATPR" does not have a component called "CR-WAERS".

but, this works fine for PP sub-table like

<b>it_matpr-pp-kaln1 = wa_mbew-kaln1.</b>

Can anybody please help me?

Thank you in advance.
