SPP : BAPI_TSSRVSCMB_CHANGEKFIGVAL not updating key figure values

Hello experts,

We are unable to use BAPI_TSSRVSCMB_CHANGEKFIGVAL to update key figure values in SPP.

BAPI run seems to be completed successfully (as I can't see any error message under the "Return" table) but still no values are getting updated under the required key figure.

Following are the details I am passing under the BAPI :

Import Parameters

1. 1.       TIMESERIESID -> TSID_PROMO

Tables

A. KEY_FIGURE

Row 1

1. KEY_FIGURE -> 1
2. KEY_FIGURE _SEMANTICS -> PROMO_STATE
3. CHAR_COMB_ID -> 1
4. TIME SEMANTICS -> MONTH

Row 2

1. KEY_FIGURE -> 1
2. KEY_FIGURE _SEMANTICS -> PROMO_STATE
3. CHAR_COMB_ID -> 2
4. TIME SEMANTICS -> MONTH

B. KEY_FIGURE_VALUE

Row 1

1. KEY_FIGURE -> 1
2. PERIOD_START -> 20140101000000
3. PERIOD_END -> 20140131235959
4. KEY_FIGURE_VALUE -> 1

C. CHAR_COMBINATION

Row 1

1. CHAR_COMB_ID -> 1
2. CHAR_SEMANTICS -> STOCKING
3. CHAR_VALUE -> “required location code”

Row 2

1. CHAR_COMB_ID -> 2
2. CHAR_SEMANTICS -> PRODUCT
3. CHAR_VALUE -> “required product code”

IF any of you have used this BAPI successfully, please suggest where can I be wrong here??

Or if there is any other way by which I can update the key figure values in SPP.

Regards,
