Abap Data dictionary Field description -

-

i'm trying query sap's data dictionary through erpconnect's abap api. code below retrieves table names , various field properties fine fails show field description. knows why?

thanks

report  zselectcommand. tables: dd02l,     dd03l,     dd02t, dd04t.  data: begin of tb_meta,     tabname   type  dd02l-tabname,     fieldname   type  dd03l-fieldname,     datatype    type  dd03l-datatype,     leng        type  dd03l-leng,     decimals    type  dd03l-decimals,     position    type  dd03l-position, desc    type  dd04t-ddtext,     end of tb_meta. data utb_meta standard table of tb_meta. data: ln_meta line of utb_meta, m1 type i, m2 type i. select     tb~tabname fld~fieldname     fld~datatype    fld~leng     fld~decimals    fld~position x~ddtext     corresponding fields of table utb_meta     dd02l tb inner join dd03l fld     on tb~tabname = fld~tabname inner join dd04t x on fld~rollname = x~rollname , x~ddlanguage = 'en'     contflag in ('a', 'c', 's')       ,      applclass <> ''      ,      tb~tabname not '/%'      ,      tb~tabname not '%_bak'     ,    tb~tabname = 'bsak'. *get run time field m1.  loop @ utb_meta ln_meta.     write:/      ln_meta-tabname      && '>>' && ln_meta-fieldname      && '>>' && ln_meta-datatype     && '>>' && ln_meta-leng     && '>>' && ln_meta-decimals     && '>>' && ln_meta-position     && '>>' && ln_meta-desc. endloop.

there different places text information of table field or structure field can stored. data element texts selecting dd04t 1 place texts. can define table components built-in data types instead of dictionary data types, texts stored in dd03t(for example)

for these reasons (technical details of dd*tables), recommend use function module ddif_fieldinfo_getinstead of rolling own dd* select. pass parameters tabname , langu, , resulting internal table dfies_tab contain information need, including texts.

i have data grid rows represent theta (0, pi) , columns represent phi (0, 2*pi) , f(theta,phi) density of dark matter @ location. wanted calculate power spectrum , have decided use healpy. what can not understand how format data healpy use. if provide code (in python obvious reasons) or point me tutorial, great! have tried hand @ doing following code: #grid dimensions nrows*ncols (subject change) theta = np.linspace(0, np.pi, num=grid.shape[0])[:, none] phi = np.linspace(0, 2*np.pi, num=grid.shape[1]) nside = 512 print "pixel area: %.2f square degrees" % hp.nside2pixarea(nside, degrees=true) pix = hp.ang2pix(nside, theta, phi) healpix_map = np.zeros(hp.nside2npix(nside), dtype=np.double) healpix_map[pix] = grid but, when try execute code power spectrum. specifically, : cl = hp.anafast(healpix_map[pix], lmax=1024) i error: typeerror: bad number of pixels if point me tutorial or edit code great. more specifications: data in 2d np array , can change numrows/...
