Some Error in FM: L_TO_CREATE_SINGLE

Question

Dear Friends,
I want to move some Material from bin to bin by FM: L_TO_CREATE_SINGLE like this:
Warehouse No.: K01
Plant: 1000
Movement Type: 999
Material No.:  PPN106789RTF122359
Batch: 0000000502
Quantity: 1.00
Unit: EA
Move From:
Storage Type: CD
Storage Bin: CD-01-03
To:
Storage Type: ZT1
Storage Bin: ZT1-01-01
Storage Type Unit: E9
I have fill in FM like:
I_LGNUM = K01
I_BWLVS = 999
I_MATNR = PPN106789RTF122359
I_WERKS = 1000
I_CHARG = 0000000502
I_LETYP = E9
I_ANFME = 1.000
I_ALTME = EA
I_SQUIT = X
I_VLTYP = CD
I_VLPLA = CD-01-03
I_NLTYP = ZT1
I_NLPLA = ZT1-01-01
but I got the error message as "Storage bin ZT1-01-01 is not a fixed bin for material PPN106789RTF122359" when executed.
But when I make it manually by Tcode: LT10 (Stock Transfer) and fill in the Selection Criteria as:
Warehouse No: K01
Stock Type: CD
Storage Bin: CD
Plant: 1000
Materiial No: PPN106789RTF122359
Movement Type: 999
Stock Transfer View: Quant
Afer execute I have Choose and tik checkbox some Item as
Storage Bin: CD-01-03  
Material No.: PPN106789RTF122359
Plant: 1000                
Avail Stock: 1
Unit: EA 
Batch: 0000000501                                  
Duration: 1     
And I have Click "Stock Transfer Foreground Icon" and fill in the Target Bin Info as
Storage Type: ZIT1
Storage Bin: ZT1-01-01
Storage Unit Type: E9
Movement type: 999
and tik the checkbox confirm immed.
When I click "Copy Button" it will make the green hightlight at that line and the TO will created.
I don't know why I transfer with FM it've got the error but do it manually it work...what's the mistake or I misunderstood somethings?
Thanks in advances,

Please advise,
