注
FI_ITEMS_MASS_CHANGE 里是
call transaction 'FB02' using bdcdata
mode bdcmode
update 'A'
messages into msgtab.
所以如果在Loop里更新一张凭证的多行会有锁定问题。
解决方法：等锁（另外手动解锁应该也可以）
data lt_seqg3 like table of seqg3 with header line.
data lv_garg like lt_seqg3-garg.
lv_garg = sy-mandt && ls_bseg-bukrs && ls_bseg-belnr && ls_bseg-gjahr.
do.
call function 'ENQUEUE_READ'
exporting
guname = sy-uname
tables
enq = lt_seqg3.
read table lt_seqg3 with key gname = 'BKPF' garg = lv_garg.
if sy-subrc ne 0.
exit.
endif.
enddo.
